Struggling like bloody mad to get ff2 & ff3 sorted. According to the sticky, you cut 26 degrees off ff2 & ff3 so that they are leaning outwards, no problem. But then to do points c & d, basically a cut that leans them back by 14 degrees, I can't get right. It's hard marking the angle on the steel when it already has a cut on it. Am I missing a trick here ? I can't get this sorted. Half considered in a moment of rage, fitting the top rails, ff1 & ff2, get the 2 69.5 mm bits cut with the 13 degree cuts tacked in, then fabricate the remainders of ff2 & ff3 to suit. Can't understand why it's a pain, it appears to be such a simple arrangement.
